CNC Lathe Machining Service CNC Steel Part Turning Steel Metal Parts Production
Stainless Steel CNC Turning Parts
CNC machining, short for computer numerical control machining, is a widely used manufacturing
process that employs automated, high-speed cutting tools to shape designs from metal or plastic
stock materials.
Common CNC machines include 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers.
These machines may employ different approaches to cut CNC parts, such as keeping the workpiece
stationary while the tool moves, keeping the tool stationary while rotating and moving the
workpiece, or moving both the cutting tool and workpiece simultaneously.
Experienced machinists operate CNC machines by programming tool paths based on the final
machined parts' geometrical specifications, which are derived from a CAD (computer-aided design)
model.
CNC machines exhibit the capability to precisely and repeatedly cut nearly any metal alloy and
rigid plastic, making them suitable for custom machined parts in a wide range of industries,
including aerospace, medical, robotics, electronics, and industrial applications.
Product Details
Material have three main categories: plastics, soft metals, and hard metals.
These materials are versatile and suitable for various machining applications.
Examples of materials used in CNC milling include aluminum, bronze, copper, ceramics, plywood,
various types of steel, stone, wood, and zinc, among others.
Certain materials, such as aluminum and mild steel, are favored by machinists due to their ease
of workability and excellent properties, making them industry standards for many applications.
| Common Materials | |
| Name | Description |
| Aluminum | High machinability and ductility, good strength-to-weight ratio. |
| Stainless steel | High tensile strength, corrosion and temperature resistant. |
| Mild steel | High machinability and weldability, high stiffness. |
| Brass | Low friction, excellent electrical conductivity, golden appearance. |
| Copper | Excellent thermal and electrical conductivity. |
| Titanium | Excellent strength to weight ratio, used in aerospace, automotive and medical industries. |
| ABS | Common thermoplastic, impact resistant, easy to machine. |
| Nylon | Excellent mechanical properties, thermal, chemical and abrasion resistant. |
| POM | High stiffness, high accuracy, low friction, easy to machine. |
Post-processing and surface finishes for CNC machining
CNC-machined parts as they emerge from the machine often exhibit visible tool marks, a feature
that may not align with your specific part requirements.
Fortunately, there exists a multitude of post-processing techniques aimed at enhancing the surface
appearance and elevating attributes such as wear resistance, corrosion resistance, and chemical
resistance.
Methods like anodizing, bead blasting, and powder coating present viable options for refining the
final presentation of your custom parts, allowing you to achieve the desired surface quality and
performance characteristics.

FAQ's
1. Why Opt for CNC Machining?
CNC machining is a rapid, precise, and adaptable manufacturing
process.
It stands out as a manufacturing solution that can deliver end-use parts efficiently, regardless
of the production volume, without the necessity of investing in costly hard tooling or elaborate
setups.
2. How long does it take to receive a quotation?
Typically, we aim to provide a response within one days upon
receiving an RFQ.
If there is a delay in generating the quote, we will promptly inform you.
3. How soon can I receive my parts?
We can produce quality parts in as little as two weeks if you
provide us with complete 2D and
3D CAD models.
However, more complex parts with special features may have longer lead times.
Request a quote to receive more precise lead times based on your specific project.
Regarding shipping, our primary method is air freight, which
typically takes a few days for delivery
from China to Europe or North America.
4. Cost Considerations for CNC Machining Materials
The cost of materials in CNC machining can fluctuate significantly
due to the extensive array
of available options.
Each material carries its unique price tag, and the inherent physical properties of each material
play a substantial role in determining machining costs.
For those seeking to manufacture metal components, Aluminum 6061 stands out as the most
cost-effective choice.
On the other hand, ABS ranks as the most budget-friendly option among materials.
As for the influence of machining complexity on costs, stainless steel serves as an illustrative
example.
Its inherent hardness, surpassing that of aluminum, renders it more challenging to machine,
consequently elevating the overall machining expenses.
